As a experienced lawnmower racer and small engine builder, I can tell you please be careful when removing governor’s out of engines that are not built for higher rpm than 3500 rpm. Most factory flywheels can/will explode at extreme rpm, that’s why all LMRA require 1/4” fan shrouds on altered engines during pre-race inspection before racing and kill switch attached to your body. Yes a flywheel spinning 5000+ rpm can explode and take very important parts of body away. Best advice is don’t play with the rpm, just swap the pulleys , upgrade the brakes and have fun. Get rid of your plastic steering wheel, That steering shaft hurts like heck when you hit it 35 mph when that steering wheel snap’s loose at the hub.
Sure , all it just takes tinkering , and a deep wallet or just find a good builder on RU-vid and copy his advice. . Hydrostat is just a hydraulic pump. but, we used a 5 spd Tecumseh Peerless 700 I believe, with a cart axle. We had a tech inspection before every race, all of us had jobs and families. Anyone can slap a bunch of stuff together and go fast, building it and living through and bragging afterwards is what is cool, anybody can wreck and get hurt. Our blower shroud was made using 1/4" x 4" metal band , shape to the outside of the blower housing , required if running a cast iron flywheel.@@poof8433
So glad you put a safety segment at the end of your video. you might wanna put that beginning explaining to people please don’t try some of this could you could , can and we’ll get hurt. You will find out as you go deeper into playing with these lawnmowers that you could take this two different directions. You could lean more towards mud bogging in the woods our go more into the need for speed and build a lawn more strictly for flat surfaces, which has a potential for higher speeds and higher engine rpm which means you’ll definitely will have to address the exploding stock/ cast iron flywheel issues. Good luck , love your vids. Your Uncle Micah sent me here.
Cool video, i have a few questions, when you put the push mower engine on the murray mower how did you hook up a pulley to the engine. And also how can you get off rust welded wheels on a lawn mower?
I use the original Bolt from the push mower blade and I just bolted on a pulley from another lawn mower I will make another video to show you guys and just use a hammer and some Rust free spray
